Jeff's mother looked at the list of options, flipping back and forth between various choices. She found the various options fascinating, and her curiousity was tingling. On a whim, she selected 'statue' options, and discovered a whole list of possibilities for different materials, and poses. A wicked smile crossed her pretty face, as she entered the necessary choices.

Moments later, Jeff's mother was a glass statue, glittering in the light, still dressed in her casual top and the panties that were her son's current form.
